GONCEALED PULLEY AND CORD FOR SASI-IES.

Application filed October 2, 1926. Serial No. 139,114.

This invention relates to pulleys designed for use upon window framesfor guiding sash cords thereover.

The invention embodies among other characteristics flange memberscarried upon the ends of the pulley mounting adapted for engagement withthe window frame to obviate the use of fastening elements.

A further object of the invention comprehendsthe disposition of saidpulleys at appropriate points within the windowframe behind the siderails of the sashes to exclude the same from view and to prevent. theingress of drafts therethrough.

lVit-h the above and other objects in view, the invention furtherconsists of the following novel features and details of construction tobe hereinafter more fully described, illustrated in the accompanyingdrawings, and pointed out in the appended claim.

In the drawing:

Figure 1 is anelevation of the window and sashes therefor partly brokenaway to illustrate the construction and application of the inventionwhen used in conjunction therewith.

Figure 2 is an end elevation of the window frame and pulleys carriedthereby.

Figure 3 is a perspective of the aforementioned pulleys.

Figure 4 is a similar view of a single pulley and mountings thereforutilized for guiding and training said sash cord to and from theaforementioned pulley.

Referring to the drawing in detail, wherein like characters of referencedenote corresponding parts, the reference character indicates a windowframe having upper and lower sashes 11 and 12 slidably mounted withinsash grooves 12 The invention contemplates slotted ferrules 13 carriedwithin the side rails of the sashes adjacent the intersections of bottomrails therewith to receive the lower knotted ends of ssh cords, such asindicated at 1 1. Grooved companion pulley wheels 15 are journaled inspaced aligned relation between elongated supporting plates 16. Saidplates are positioned within cutouts or openings provided in the groovesfor the sashes and which terminate at their inner ends in oppositelydisposed flange portions 17 lying flush with said grooves. The innermostof the pulley wheels is disposed wholly within the window frametldjittfillll said grooves. The remaining end of the plates are disposediuiwardly and obliquely from said flangeportions 17 and terminate toprovide an alnitment 18 adapted to he flush with the opposedside of thewindow frame in contraalistinction to the flange portions 17.

The sash cord 14, is then passed over the first mentioned pulley andbeneath the second mentioned pulley" and extended upwardly therefrom andtrained over a single pulley 19 of similar construction and journaledbetween spaced ears 20 carried by a plate member 21. Said plate 21 ismounted upon the corresponding side of the window frame with respect tothe abutment 18 through the instrumentality of a fastening element, notshown, passed through an opening 22 in one end while the opposed endthereof provides inwardly disposed teeth 23 which are driven within theparticular portion of said frame. Obviously, sash weights, such asindicated at 2 1, are tied upon the remaining extremities of the sashcords.

Either of the sashes, whether they be moved to open or closed positionsexclude the pulleys and openings, tln'ough which. the same are mounted,from view thereby obviating any possibility of the ingress of draftstl'ierethrough. The a-r 'an; gen'1ent of the pulley wheels 15 and themanner of training the sash cords theroover will also prevent, to amarked degree, any apparent difiiculty generally experienced by the sashcords riding out of the grooves of the pulleys.

The invention is susceptible of various changes in its'form,proportions, and minor details of construction, and the right is hereinreserved to make such changes as properly fall within the scope of theappended claim.

Having thus described my invention, what is claimed is:

A sz sh balance comprising a frame provided with. outwardly and upwardlyinclined openings located within sash grooves therefor, plates carriedwithin the openings being provided with laterally oppositely andoutwardly disposed flange portions upon the lower ends thereof and lyingflush within the bottoms of the grooves, the remaining portions of theplates beingextending upwardly and obliquely from the flange portions,an abutment common to the plates 5 being adapted for engagement with theouter sides of the grooves, and pulleys journaled between the platesadapted to train sash ARTHUR O.
